JOHN J. RENOHARD, OF DETROIT, MICHIGAN.

LUBRICATOR.

SPECIFICATION formingpart of Letters Patent No. 264,477, dated September 19, 18-82,

Application led March 24, 1882. (No model.)

To cit whom it may concern:

Be it known that' I, JOHN J. RENGHARD, a citiz'en of the United States, residing at Detroit, in4 the county ot NVayne and State of Michigan, have invented certain new and useful Improvements in Lubric'a tors; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in that class of lubricators for which Letters Patent ot' the United States Na/1,426 Weregranted to myself and J. V. Renchard, November 14, 1876, the operation of which lubricator was ascer-tained by the descent ot water, drop by drop, through the oil. By my improvement the operation is ascertained by observing the ascent of the oil in like manner through the Water.

The construction and operation of my improved lubricator are further explaiuedby reference to the accompanying drawing, which represents a vertical section of the same. l

A is the supporting-truuk, which' is provided with steam-passage B and oil-passage O.

E is the condensing-chamber. A

F is a steam-tube.

Gr is a waterLseal or Siphon-tube.

H -is the oil-chamber.

' Steam enters the condenser through steampassage B and tube F.

Water is conducted from the condenser to and discharged in the oil-chamber H through the siphontube G. The Siphon-tube G forms a Watertrap, which prevents oil passing into the condenser.

The parts thus described are substantially like those shown in our said patent, both in construction and operation.

Iis a glassindicator-tube, which is connected to theoil-receptacle attop and bottom by glass cages J and K,'in the ordinary manner.

In operating my device the tube I is lled with Water and the receptacle H is iirst filled with oil, which is introduced through glass cage J. As Waterdescendsthrough tubeGthe oil is iloated over the mouth of oil-tube L,

when it descends through said tube and passes into glass cage K, from which it is discharged into thelowerend of theindica-tor-tube I, when, owing to its less specific gravity,it rises gradually through the Water in tube I and escapes into the lower compartment, M, of the gia-ss cage J, from which it is forced out through passages N and O into the steam-pipes of the engine. The glass cage J is closed bya double stopper, O, the lower end, P, of which closes the en trance in diaphragm c to chamber M, and the central part, R, closes the mouth ot the glass cage. Thus when the stopper O is in -place the passage between theoil-chamberand the indicator-tube is closed, andtheoilis therefore com pelled to pass out, as described ,th rough passageO Whendesiroustoillthereceptacle H with oil, stopper O being removed,theneck of an oil-ller is inserted at an angle through the top of the glass cage J and the passage S. As every drop of Water which passes through the tube G displaces adrop of oil, the oil thus displaced passes, drop by drop, up through the indicator-tube l, as described, and the feed is thereby readily ascertained and may be regulated by the regulating-valve T. The glass cage K is divided into tivo compartments by the diaphragm a., which diaphragm prevents the water in the glass tube I from sinking beneath the oil in compartment I). The oil in compartment b is led to and discharged into the lower end of tube I by tube d, from which tube it escapes, drop by drop, and passes up through the Water, as mentioned.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In lubricators, the combination of condensing-chamber E, oil-reservoir H, having a supporting-truuk, A, provided with separate steam and oil passages, with glass cage J, sub-v divided into two compartments by diaphragm c, and provided with double stopper O, glass tube l, glass cage K,having diaphragm a, tube d, and oil-tube L, said glass cage J being provided with passage S,comn1unicating with the oil-reservoir, and tube or passage N, communieating with the oil-passage O, all substantially as and for the purpose specified.

2. In lubricators, the glass cage J, having IOOv diaphragm e, stopper O, and passages S and N, formed inthe connecting trunk or coupling of said cage, said stopper closing communication between tile said passages and between the glass tube and said passage S, substantially as set forth.

3. The combination, with the condensingehamber and oil-receptacle, of a lubrieator provided with a single supporting-trunk having separate steam and oil passages and verticallyarranged Water-seal and oil-tubes loea ted therein, of the glass cages J and K, said cage K being provided with oil-duet communicating from said oil-tube to the side glass tube, said glass eage J being provided with diaphragm c, double stopper O, and duet N, said stopper being adapted to simultaneously close the ea ge, and comlnunieatingbetween said oil-receptacle and said glass tube, all substantially as set forth.

ln testimony whereof I aiiix my signature in presence of two witnesses.
